typical ore process for gold mining

The Mining Process Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands.

Gold mining

Historically, mercury was used extensively in placer gold mining in order to form mercury gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small scale gold mining (ASGM), often clandestine, gold prospecting.
